Methods of Gene Transfer in Plants: 2 Methods
Silicon Carbide Fibre-Mediated Transformation: The silicon carbide fibres (SCF) are about 0.3-0.6 pm in diameter and 10-100 pm in length. These fibres are capable of penetrating the cell wall and plasma merane, and thus can deliver DNA into the cells.
Nano Silicon Carbide Whiskers | Satnanomaterial
1)Silicon carbide whiskers should be pre-dispersed as much as possible before use. They should be mechanically and ultrasonically dispersed with water, ethanol, etc., and then mixed with the matrix material. 2) The amount of silicon carbide whiskers added to
Preparation and Synthetic Mechanism of Silicon Carbide …
The effects of sintering temperature and holding time on β-SiC nanometer whiskers were investigated and the synthetic mechanism was studied. It was revealed that the β-SiC nanometer whiskers, with the diameter of 50-80nm and the aspect ratio of 50-300, can be prepared at 1300°C for 60 min.
